2 Factory 22 Apr 2014 Introduction to the Report The following report contains a site profile and summary of non-conformities identified during an onsite assessment commissioned by the Alliance for Bangladesh Worker Safety (Alliance) and conducted by a third-party Qualified Assessment Firm (QAF). The assessment was conducted against the Alliance for Bangladesh Worker Safety Assessment Protocols (APs) and Fire Safety and Structural Integrity Standard, which is harmonized with the factory assessment guidelines developed by Bangladesh University of Engineering and Technology (BUET) for the Bangladesh National Tripartite Plan of Action (NTPA). The goal of the Alliance process is to provide clear and practical technical requirements by which Bangladeshi Ready Made Garment (RMG) Factories producing for Alliance members may be consistently and fairly evaluated for fire, structural, and electrical safety in a non-duplicative manner. Each assessment will prompt action plans that will be used by RMG factories to systematically and sustainably improve safety conditions for garment workers. Beyond tracking and reporting on action steps taken in a transparent manner, the Alliance organization and its members will seek to further support factory improvements through technical assistance, training, implementation support for functional Worker Committees, and in some cases financial assistance and wage support for workers if factories are closed for remediation. The contents of the report do not constitute a guarantee of compliance with the applicable laws, the Alliance Standard or the absolute or continued safety against fire, electrical and/or structural integrity issues that may lead to injury or loss of life. The report is designed to provide a non-exhaustive summary of risk issues, based on a limited sampling and duration of time onsite by the named QAF. Neither the QAF nor the Alliance can certify or guarantee the quality, outcome, or effectiveness of actions taken in response to the report.

5 22 Apr 2014 ASSESSMENT FINDINGS Structural System Design If the structure has been previously expanded, was the structural impact on the entire structure analytically evaluated and confirmed by a qualified structural engineer. One extra floor was added in 2011 in the old part of the building and the new part of the building was added in 2013, but the structural impact on the entire structure was not analytically evaluated by a qualified structural engineer. Document Review: ASP 1.0 Have a qualified structural engineer complete an analytical evaluation of the structural impact of the addition. Reference Alliance Standards Part 8 Section 8.1 Applicability of Building Code. Are credible structural design documents available for review and kept on site? Non-Compliance Level: 1 For new part of the building the structural drawings is credible but there are no detail drawings for old part of the building so credibility check can be possible at this stage of investigation. Document Review: Structural drawings of old part and new part of the building Have a qualified structural engineer prepare credible as-built documents of old building based on the requirements of Part 8 Section 8.19 of the Alliance Standard. Alliance Standard Part 8 Section 8.19 Required Structural Documentation for New and Existing Factories Can credible structural documentation indicating general conformance with 2006 BNBC or other comparable applicable international model building code be produced? The Alliance for Bangladesh Worker Safety Page 5/10

6 22 Apr 2014 Non-Compliance Level: 1 For new part of the building they use BNBC But the old part of the building was built before There was no indication of use of any international building code shown in the drawing. Document Review: Structural design drawings of new part and old part of the building Engage a qualified structural engineer to develop the required documents for old part of the building to confirm the structural integrity of the buildings. Documents must comply with Alliance Standard Part 8 Section 8.19 and Reference Alliance Standards Part 8 Section 8.2 Structural Integrity of Existing Factory Buildings Can documentation be provided that the building is compliant with the requirements for wind loading and storm surge loadings as detailed in BNBC Part 6 Section 1.5.3? Non-Compliance Level: 1 The new part of the building is compliant with the wind loading and storm surge loadings requirements as detailed in BNBC Part 6 Section For old part wind load and storm surge loading are not mentioned in the drawings. Document Review: Structural design drawings of new part and old part of the building Engage a qualified structural engineer to confirm satisfactory structural performance of the old part of the building under wind loading BNBC Part 6 Section 1.5. Compliance may be waived if the Factory Owner provides satisfactory evidence of a cyclone operations plan that includes full evacuation of the factory in advance of any approaching cyclone" Are Certificates of Occupancy available for review?
